Though Bridgeport is less than 400 miles from LA, you should plan on about five days, maybe more, to explore the Owens Valley, and even that will just scratch the surface. Come prepared for anything in terms of weather. In the summer, temperatures often reach the 90s and even top 100 down in the valley, but a ride into the mountains can take 30 degrees off the temperature. Temperatures for our late-September ride were forecast to range from the mid-20s (at night in the mountains) to 90 (mid afternoon on the Valley floor), and they probably just about reached those extremes in the areas we rode through. You can ride as far as Bishop during most of winter, but the chance of encountering snow increases quickly north of that and at higher altitudes. During the summer, you may encounter localized thunderstorms in the mountains, though widespread rain is rare.
